3 to 5 illustrate the overall structure of the dust collector and the flow of air and impurities in the dust collector. The detailed configuration related to the characteristics of the present invention will be described later with reference to FIGS. 6 to 8 .

FIG. 3 is a perspective view of a dust collector 200 related to an embodiment of the present invention. FIG. 4 is a cross-sectional view showing the internal structure of the dust collector 200 shown in FIG. 3 . FIG. 5 is a conceptual diagram of the internal structure of the dust collector 200 shown in FIG. 4 viewed from another direction.

The dust collecting device 200 includes a first cyclone separator (cyclone) 205 , a second cyclone separator 250 , a first dust storage part 210 , a second dust storage part 220 , a lower cover part 230 and a compression device 240 . The dust collecting device 200 shown in the figure can be applied to the upright vacuum cleaner 1 illustrated in FIG. 1 and FIG. 2 . However, the structure of the dust collector 200 demonstrated in this specification is not limited to application to the upright vacuum cleaner 1, It is applicable also to a horizontal vacuum cleaner.

Referring to FIGS. 3 to 5 , the dust collecting device 200 provided in the present invention has a structure capable of separately collecting dust and fine dust and simultaneously discharging the collected dust and fine dust.

Air and impurities flow into the inlet 201 of the dust collecting device 200 by the suction force generated in the suction motor of the vacuum cleaner. The air flowing into the inlet 201 of the dust collector 200 flows along the flow path, is filtered in the first cyclone separator 205 and the second cyclone separator 250 in sequence, and is discharged through the outlet 202 . Dust and fine dust separated from the air are collected by the dust collecting device 200 .

A cyclone separator refers to a device that separates particles by means of centrifugal force acting on a powder through gyrating motion. The cyclone separator separates impurities such as dust and fine dust from the air flowing into the cleaner main body by suction. In this manual, relatively large dust is called "dust", relatively small dust is called "fine dust", and dust smaller than "fine dust" is called "ultrafine dust".

In the dust collecting device 200 shown in FIG. 3 , the first cyclone separator 205 is formed by a first dust bucket 211 , a second dust bucket 221 and a mesh filter (mesh filter) 261 . The first cyclone separator 205 separates dust from the air flowing into the dust collector 200 for the first time. The air and impurities flowing into the first dust storage part 210 through the inlet 201 of the dust collecting device 200 will be separated from the air by the first cyclone separator 205 .

Under the action of centrifugal force, the relatively heavy dust spirally moves in the area between the inner peripheral surface of the first dust bucket 211 and the mesh filter 261 , and gradually flows downward. Below the mesh filter 261 is formed a vane 265 formed with a spiral flow path to guide the swirling movement of dust. Dust separated from the air is guided by the impeller 265 provided at the lower end of the mesh filter 261 to be collected into the first dust storage part 210 .

The criterion for distinguishing the size of dust and fine dust can be determined by the mesh filter 261 . Impurities having a size of holes that can pass through the mesh filter 261 are classified as fine dust, while impurities that cannot pass through the holes of the mesh filter 261 are classified as dust.

Based on the first cyclone separator 205 and the second cyclone separator 250, the dust collecting device 200 can be divided into a first part 200a configured with the first cyclone separator 205 and a second part configured with the second cyclone separator 250 200b. The inlet 201 of the dust collecting device 200 is formed on the upper part of the first part 200a, and the outlet 202 of the dust collecting device 200 is formed on the upper part of the second part 200b.

Air and fine dust whose particles are smaller than dust can pass through the holes of the mesh filter 261 . Air and fine dust, which are relatively lighter than dust, may flow into the space between the mesh filter 261 and the second dust bucket 221 under the suction force of the suction motor. Air and fine dust flow from the first part 200 a to the second part 200 b through the connection flow path 260 formed between the mesh filter 261 and the outer peripheral surface of the second dust bucket 221 .

The internal structure of the dust collector 200 can be confirmed with reference to FIG. 4 .

The air and fine dust flowing to the second part 200b through the connection flow path 260 are distributed to the plurality of second cyclones 250 arranged in a circle at the periphery of the second part 200b. The principle of the second cyclone separator 250 is the same as that of the first cyclone separator 205, and it also separates fine dust from the air by centrifugal force.

The air and fine dust are spirally swirled in the second cyclone separator 250 .

The air relatively lighter than the fine dust is discharged toward the upper part by the suction force of the second cyclone 250 . In addition, the air is discharged through the outlet 202 formed in the upper portion of the second part 200b. A porous pre-filter (pre-filter) 280 is provided on the flow path leading from the second cyclone separator 250 to the outlet 202 of the dust collector 200 . The pre-filter 280 is used to filter ultra-fine dust from the air.

An upper cover portion 270 is formed on an upper portion of the dust collector 200 . When the upper cover part 270 is opened, the pre-filter 280 will be exposed. The pre-filter 280 may be separated from the dust collecting device 200 to facilitate washing thereof.

Relatively small fine dust is discharged to the lower part of the second cyclone 250 . The fine dust falls under the force of gravity and is collected in the second dust storage part 220 . A sloped portion 222 connected to the second dust storage portion 220 is formed at a lower portion of the second dust storage portion 250 . The flow of fine dust is guided from the second cyclone 250 to the second dust storage part 220 by the action of the above-mentioned inclined part 222 .

A diaphragm 290 is formed at a boundary between the first portion 200a and the second portion 200b. Diaphragm 290 is used to create a unidirectional flow. The membrane 290 may be surrounded by the second cyclone separator 250 . Without the diaphragm 290, the fine dust discharged to the lower portion of the second cyclone 250 may flow to the inlet side of the second cyclone 250 again by the suction force of the suction motor. The diaphragm 290 serves to block the flow of fine dust flowing toward the inlet side of the second cyclone 250, thereby preventing this phenomenon from occurring.

Referring to FIG. 5 , a housing 251 for fixing the second cyclone separators 250 may be formed at the periphery of the plurality of second cyclone separators 250 arranged in a circle. The frame 251 may be integrated with the second cyclone separator 250 . The second cyclone separator 250 may be formed such that its inner diameter becomes narrower as it goes downward. With such a structure, even if the upper parts of the second cyclone separators 250 are in contact with each other, the lower parts of the second cyclone separators 251 can be separated from each other. In addition, a space through which air and fine dust can pass is formed between the second cyclone separators 251 adjacent to each other.

The diaphragm 290 does not cover the space formed between the second cyclone separators 250 . A connecting flow path 260 for forming a flow path joining from the first part 200 a to the second part 200 b will be joined to the space between the second cyclone separators 250 . Thus, air and fine dust may flow from the first part 200a to the second part 200b through the space between the second cyclone separators 250 as shown by the arrows in FIG. 5 . The fine dust flowing to the second part 200 b may be distributed to the second cyclone 250 in a space surrounded by the second cyclone 250 .

Referring again to FIGS. 3 and 4 , the first dust storage part 210 is used to collect the dust separated from the air for the first time by the first cyclone separator 205 . The first dust storage part 210 is formed in a ring shape between the inner peripheral surface of the first dust bucket 211 and the outer peripheral surface of the second dust bucket 221 . The bottom surface of the first dust storage part 210 is formed by the lower cover part 230 , and the dust is mainly accumulated on the lower cover part 230 .

The first dust bucket 211 and the second dust bucket 221 are structural elements forming the first dust storage part 210 . The first dust bucket 211 forms the appearance of the dust collecting device 200 , and the second dust bucket 221 is disposed inside the first dust bucket 211 . The first dust bucket 211 and the second dust bucket 221 may be formed in a cylindrical shape as shown in FIG. 3 .

The second dust storage part 220 is configured to be surrounded by the first dust storage part 210 . The second dust storage part 220 can be disposed in the middle of the first dust storage part 210 as shown in FIG. 3 . The second dust storage part 220 is used to collect the fine dust separated from the air for the second time by the second cyclone separator 250 . Different from the first dust storage part 210 formed by the first dust bucket 211, the second dust bucket 221 and the lower cover part 230, the second dust storage part 220 is formed by the second dust bucket 221 and the lower cover part 230. formed.

The lower cover part 230 is combined with the first dust bucket 211 through a hinge 235 and forms the bottom surfaces of the first dust storage part 210 and the second dust storage part 220 . The discharge port of the first dust storage part 210 is kept airtight by the lower cover part 230 , so the dust accumulated in the first dust storage part 210 does not leak to the outside of the dust collecting device 200 . And, the outlet of the second dust storage part 220 is also kept airtight by the lower cover part 230, therefore, the dust accumulated in the second dust storage part 220 will not leak to the first dust storage part 210 or the bottom of the dust collecting device 200. external.

If the dust accumulated on the lower cover part 230 is scattered without being collected in one place, the dust accumulated on the lower cover part 230 may be scattered or discharged out of a target place during the process of dumping the dust. In order to solve such a problem, the present invention uses the compressing device 240 to compress the dust collected in the first dust storage part 210 .

At least a part of the compression device 240 is rotatably connected to the lower cover part 230 . The compression device 240 reciprocates along the outer peripheral surface of the second dust bucket 221 to compress the dust collected in the first dust storage part 210 . The dust collected in the first dust storage part 210 will be compressed by the compression device 240 and collected in a part of the first dust storage part 210 . Thereby, in the process of throwing away the dust, it is possible to suppress the scattering of the dust, and significantly reduce the possibility of it being discharged out of the target.

FIG. 6 is an isolated perspective view of the dust collector 200 .

As shown in FIG. 6 , the discharge port of the first dust storage part 210 and the discharge port of the second dust storage part 220 may form openings facing the same direction. The lower cover part 230 is rotated by the hinge 235 to simultaneously open the first dust storage part 210 and the second dust storage part 220 to simultaneously discharge dust and fine dust.

The lower cover part 230 includes a first cover 231 and a second cover 233 .

The first cover 231 is combined with the first dust bucket 211 through a hinge 235 . The first cover 231 is used to open and close the discharge port of the first dust storage part 210 . The first cover 231 has a first sealing member 232 on the outer peripheral surface for closing the discharge port of the first dust storage part 210 . The first sealing member 232 is formed in a ring shape corresponding to the inner peripheral surface of the first dust bucket 211 . When the first cover 231 is combined with the first dust bucket 211, at least a part of the first sealing member 232 is inserted into the inside of the first dust storage part 210, and is elastically deformed by being compressed by the inner peripheral surface of the first dust bucket 211. . Under the action of the first sealing member 232 , the first cover 231 may close the discharge port of the first dust storage part 210 .

The second cover 233 is connected to the first cover 231 , and opens and closes the outlet of the second dust storage part 220 as the first cover 231 rotates through the hinge 235 . Since the second cover 233 is connected to the first cover 231 , when the first cover 231 is rotated by means of the hinge 235 , the second cover 233 will also rotate together with the first cover 231 . Thus, the lower cover part 230 can simultaneously open the first dust storage part 210 and the second dust storage part 220 .

A second sealing member 234 is provided on the outer peripheral surface of the second cover 233 for closing the discharge port of the second dust storage part 220 . The second sealing member 234 is formed in a ring shape corresponding to the inner peripheral surface of the second dust bucket 221 . When the first cover 231 closes the first dust bucket 211 , at least a portion of the second sealing member 234 is inserted into the second dust storage part 220 and elastically deformed by being compressed by the inner peripheral surface of the second dust bucket 221 . Under the action of the second sealing member 234 , the second cover 233 may close the discharge port of the second dust storage part 220 .

The dust collecting device 200 includes a fastening portion 236 for preventing the first cover 231 from detaching from the first dust bucket 211 until the fastened state is released due to external force. The fastening part 236 combines the first dust bucket 211 and the first cover 231 at the opposite side of the hinge 235 .

As the fastening part 236, for example, a push-button type hook can be applied. When the first cover 231 is rotated around the hinge 235 to make it close to the first dust bucket 211, the hook will naturally be stuck on the first cover 231, thereby fastening the first dust bucket 211 and the first cover 231. When the user presses the button, the fastening state of the hook is released, and the first cover 231 rotates around the hinge 235 to open the first dust storage part 210 and the second dust storage part 220 at the same time.

When the user needs to discharge dust and fine dust from the dust collecting device 200 , the fastening state by the fastening portion 236 needs to be released. While the fastening state by the fastening part 236 is released, the lower cover part 230 rotates around the hinge 235 under the force of gravity. Thus, the user can easily discharge the dust collected in the first dust storage part 210 and the fine dust collected in the second dust storage part 220 at the same time. Therefore, the present invention can eliminate the inconvenience caused by the need to pour out dust and fine dust twice.

In particular, the present invention includes a compressing device 240 for compressing the dust collected in the first dust storage part 210 . Dust collected in the first dust storage part 210 is compressed to a part of the first dust storage part 210 under the action of the compression device 240 . Therefore, when using the compressing device 240 and the lower cover part 230 of the present invention, the convenience that the compressed dust and the fine dust can be easily thrown away at the same time is provided to the user.

The detailed structures of such a compression device 240 and the lower cover portion 230 will be described with reference to FIGS. 6 and 7 together.

FIG. 7 is a cross-sectional view of the dust collector 200 .

Referring to FIG. 6 and FIG. 7 together, the compressing device 240 includes a rotating gear 241 , a first rotating part 242 , a second rotating part 243 and a dust compressing rotating disk 244 .

The rotary gear 241 is coupled to the first cover 231 so as to be exposed to the outside of the dust collector 200 . The rotation gear 241 is not shown in FIG. 6 but is shown in FIG. 7 . When the dust collecting device 200 is combined with the main body of the vacuum cleaner, the rotating gear 241 will naturally mesh with the gear (not shown) of the main body of the vacuum cleaner.

As described with reference to FIG. 1 , the dust collecting device 200 may be installed on or separated from the main body of the vacuum cleaner. Referring to FIG. 7 , a guide part 231' may be formed on the first cover 231 to guide a designated position where the dust collecting device 200 is coupled to the cleaner body. A guide part 231' is protruded from the first cover 231. A space for accommodating the dust collector 200 is formed in the main body of the cleaner, and a groove corresponding to the above-mentioned guide part 231' may be formed in the space for accommodating the dust collector 200. When the dust collecting device 200 is combined with the main body of the vacuum cleaner, the dust collecting device 200 may be guided by the guide part 231' and the groove to be installed at a designated position. When the dust collecting device 200 is installed on the main body of the vacuum cleaner, the rotating gear 241 will naturally mesh with the gear of the main body of the vacuum cleaner.

The gear of the cleaner main body transmits driving force from the driving part of the cleaner main body. The drive unit of the cleaner body includes, for example, a motor. When a reaction force is applied in a direction opposite to the direction of rotation of the motor, the motor can convert the direction of rotation to the opposite direction. The motor of the driving part is distinguished from the suction motor.

Since the gear of the cleaner body is meshed with the rotation gear 241 , the driving force transmitted in the gear of the cleaner body is also transmitted to the rotation gear 241 . In addition, the rotation gear 241 is rotated by the driving force transmitted through the gear of the cleaner main body.

The first rotating part 242 is arranged on the opposite side of the rotating gear 241 with respect to the first cover 231 . Thus, when the first cover 231 is fastened to the first dust bucket 211 by the fastening portion 236 , the rotating gear 241 is exposed to the outside of the dust collecting device, and the first rotating portion 242 is disposed inside the dust collecting device 200 .

The first rotating part 242 passes through the first cover 231 and is connected to the rotating gear 241 so as to rotate together with the rotating gear 241 when the rotating gear 241 rotates. As shown in FIG. 7 , the first rotating part 242 may also be integrally formed with the rotating gear 241 .

The second rotating part 243 is relatively rotatably combined with the second dust bucket 221 . For example, as shown in Figure 6, the end portion of the second dust bucket 221 is formed in a ring shape, and the second rotating part 243 is formed in a ring shape corresponding to the end portion of the second dust bucket 221, so that it can be combined with the above-mentioned second dust bucket 221 ends. Even if the second dust bucket 221 is fixed, the second rotating part 243 can relatively rotate at the end of the second dust bucket 221 .

Referring to FIG. 6, the first rotating part 242 has a plurality of protrusions 242a formed radially from the center of rotation. In addition, the second rotating part 243 has a receiving part 243a for receiving an end part of the protruding part 242a on the inner peripheral surface. In a state where the first cover 231 is fastened to the first dust bucket 211 by the fastening part 236, the end of the protruding part 242a will be inserted into the receiving part 243a. Thus, the first rotating part 242 and the second rotating part 243 are engaged with each other so as to be rotatable at the same time.

The protruding part 242a and the receiving part 243a have corresponding inclined surfaces 242b, 243b respectively, so that they can also be engaged with each other by tilting and sliding at positions that are not completely engaged with each other. In the process of the lower cover part 230 closing the discharge port of the first dust storage part 210 and the discharge port of the second dust storage part 220, the first rotating part 242 and the second rotating part 243 will engage with each other. The part 242a can be inserted into the receiving part 243a at a position that is not fully engaged with each receiving part 243a. Even so, since the protruding portion 242a and the receiving portion 243a have inclined surfaces 242b, 243b, the first rotating portion 242 and the second rotating portion 243 can slide relative to each other by means of the inclined surfaces 242b, 243b, thereby enabling natural fit. (complete engagement).

Referring to FIG. 7 , the second dust bucket 221 is spaced apart from the first cover 231 . The second cover 233 forms a stepped portion d with the first cover 231 in order to be combined with the second dust bucket 221 . The first rotating part 242 and the second rotating part 243 are configured to rotate in a space formed between the second dust bucket 221 and the first cover 231 . In addition, the second cover 233 is disposed above the rotation center axis 242' of the first rotation part 242, and can be inserted into the second dust storage part 220. The reason why the second cover 233 and the first cover 231 form a stepped portion d is to insert it into the second dust storage part 220 .

When the second cover 233 rotates with the first rotating part 242 , fine dust collected inside the second dust storage part 220 may leak to the outside of the first dust storage part 210 or the dust collecting device 200 . In order to prevent this from happening, the second cover 233 is relatively rotatably connected to the first rotating part 242 . In addition, when the first rotating part 242 rotates, the second sealing member 234 restricts the rotation of the second cover 233 by the frictional force formed by contacting the inner peripheral surface of the second dust bucket 221, thereby closing the second dust storage part. 220 outlet. Thus, even if the first rotating part 242 rotates, the second cover 233 may hardly rotate due to the second sealing member 234 . The structure as described above can prevent the fine dust collected inside the second dust storage part 220 from leaking.

The dust compression rotating disc 244 is connected to the second rotating part 243 and rotates together with the first rotating part 242 and the second rotating part 243 when the rotating gear 241 rotates. As shown in FIG. 6 , the dust compression rotating disk 244 may be integrally formed with the second rotating part 243 . The dust compression rotary disk 244 compresses the dust collected in the first dust storage part 210 by reciprocating.

The aforementioned driving part (for example, motor) of the cleaner main body can convert the rotation direction to the opposite direction when receiving the reaction force in the opposite direction to the rotation direction that provides the driving force. The dust compression rotating disk 244 transmits the driving force through the gear of the cleaner main body, the rotating gear 241 , the first rotating part 242 and the second rotating part 243 . Accordingly, when the rotation direction of the drive unit is reversed, the rotation direction of the dust compressing rotary disk 244 is also reversed.

The dust collecting device 200 also includes a dust compression fixed disk 245 .

The dust compression fixing disk 245 is formed in a region between the inner peripheral surface of the first dust bucket 211 and the outer peripheral surface of the second dust bucket 221 . The dust compression fixed disk 245 may be formed in substantially the same shape as the dust compression rotary disk 244 .

The dust compression fixed disk 245 is used to guide the reciprocating movement of the dust compression rotary disk 244 . When the dust compression rotating disk 244 rotates along the outer peripheral surface of the second dust bucket 221 , it will generate a reaction force when it is close to the dust compression fixed disk 245 . As a result, the driving part inside the main body of the vacuum cleaner will rotate in the opposite direction to the original rotation, and the gears of the main body of the vacuum cleaner, the rotating gear 241, the first rotating part 242 and the second rotating part 243 connected to the driving part in sequence will also rotate in the opposite direction. . In addition, the dust compressing rotating disc 244 connected to the second rotating part 243 will also rotate in a direction opposite to the original rotating direction.

As a result, the dust compression rotary disk 244 will repeatedly perform reciprocating motions of rotating from one side to the other side and then from the other side to one side with the dust compression fixed disk 245 as a reference. In addition, the dust collected inside the first dust storage part 210 is compressed on both sides of the dust compression fixed disk 245 by the reciprocating motion of the dust compression rotary disk 244 .

The dust compression fixed disk 245 is used to limit the movement of the compressed dust. What is different from the dust compression rotating disk 244 is that the dust compression fixed disk 245 is in a fixed state, therefore, the movement of the dust compressed on both sides of the dust compression fixed disk 245 will be restricted by the dust compression fixed disk 245. Thus, even if the dust compressing rotary disc 244 continues to reciprocate in the first dust storage part 210 , the dust compressing fixed disc 245 can prevent the compressed dust from scattering.

The rotation of the compression device 240 may be guided by the guide rail 223 and the guide protrusion 243c. The second dust bucket 221 has a guide rail 223 for guiding the rotation of the second rotating part 243 on the outer peripheral surface. In addition, the second rotating part 243 has a guide rail protrusion 243c for being inserted into the guide rail 223 . The second rotating part 243 can rotate along the guide rail 223 at the discharge port of the second dust storage part 220 through the guide rail protrusion 243c.

The dust collecting device 200 may further include a bearing 249 for lubricating the rotation of the compression device 240 . The bearing 249 is coupled to the rotation center shaft 242' of at least one of the rotation gear 241 and the first rotation part 242. The rotation gear 241 and the first rotation part 242 may be integrally formed, and the bearing 249 may have one or more.

FIG. 8 is a cross-sectional view of dust collector 200 showing a state in which lower cover portion 230 is opened.

During the operation of the vacuum cleaner, the compression device 240 continuously compresses the dust collected inside the first dust storage part 210, so the dust will exist in a compressed state at the end of the operation of the vacuum cleaner. On both sides of the dust compression fixed disk 245.

In order to discharge the dust and fine dust collected inside the dust collecting device 200, when the user unfastens the fastening part 236, as shown in FIG. 8, the lower cover part 230 will rotate around the hinge 235 to open. The first dust storage part 210 and the second dust storage part 220 .

When the first dust storage part 210 and the second dust storage part 220 are opened, the first rotating part 242 and the second rotating part 243 which are originally engaged with each other will move away from each other. Since the first rotating part 242 is combined with the lower cover part 230 , it will move along with the lower cover part 230 . The second rotating part 243 remains connected to the second dust bucket 221 . The guide rail 223 and the guide protrusion 243 c may serve to guide the rotation of the second rotating part 243 and also serve to prevent the second rotating part 243 from being separated from the second dust bucket 221 .

The lower cover part 230 forms the bottom surface of the first dust storage part 210 and the second dust storage part 220, and will open the first dust storage part 210 and the second dust storage part 220 at the same time, therefore, the structure of the present invention can discharge the second dust storage part at the same time. Dust collected in the first dust storage part 210 and fine dust collected in the second dust storage part 220 . In addition, since the dust is in a state of being compressed by the compressing device 240, it is possible to prevent the dust from scattering and to be easily discharged by gravity.

The present invention can greatly improve the convenience of dust discharge by compressing the dust by the compression device 240 and simultaneously discharging the dust and fine dust by the lower cover part 230 .

Another embodiment of the present invention will be described below.

Fig. 9 is an isolated perspective view of a dust collecting device 300 related to another embodiment of the present invention.

In the structure of the dust collecting device 300, the structure common to the foregoing embodiment will be replaced by the foregoing description.

As shown in FIG. 9 , the dust collecting device 300 includes a first dust bucket 311 , a second dust bucket 321 and a lower cover 330 .

The dust collecting device 300 shown in FIG. 9 compresses the fine dust collected in the second dust storage 320 in addition to the dust collected in the first dust storage 310 . The compressing device 340 includes a rotating gear (not shown), a first rotating part 342 , a second rotating part 343 , a dust compressing rotating disc 344 and a fine dust compressing rotating disc 346 .

The fine dust compression rotating disk 346 is connected to the first rotating part 342, and rotates together with the first rotating part 342 and the second rotating part 343 when the rotating gear rotates. Specifically, the rotation center shaft 346' of the fine dust compression rotating disc 346 can pass through the second cover 333 to be connected to the rotation center shaft (not shown) of the first rotating part 342. When the first rotating part 342 rotates, the fine dust compressing rotating disk 346 will also rotate at the original position.

The fine dust compression rotary disk 346 reciprocates inside the second dust storage part 320 and compresses the fine dust collected in the second dust storage part 320 . The principle of compressing the fine dust by the fine dust compressing rotary disc 346 is the same as the principle of compressing the dust by the dust compressing rotary disc 344 .

The fine dust compression rotating disk 346 is connected to the first rotating part 342 , and the first rotating part 342 moves along with the first cover 331 . Thus, the fine dust compression rotating disk 346 will also move along with the first cover 331 . Specifically, when the first cover 331 is rotated by the hinge 335 to close the first dust storage part 310 and the second dust storage part 320 , the fine dust compression rotating disk 346 will be inserted inside the second dust storage part 320 . On the contrary, when the first cover 331 is rotated by the hinge 335 to open the first dust storage part 310 and the second dust storage part 320 , the fine dust compression rotating disk 346 will be taken out from the inside of the second dust storage part 320 .

The dust collecting device 300 also includes a fine dust compression fixed disk 347 .

The fine dust compression fixed disk 347 is fixed inside the second dust storage part 320 . The reason why the fine dust compression fixed disk 347 is fixed inside the second dust storage part 320 is to guide the reciprocating motion of the fine dust compression rotary disk 346 and limit the movement of the fine dust compressed by the fine dust compression rotary disk 346 . The principle of the fine dust compression fixed disk 347 is the same as that of the aforementioned dust compression fixed disks 245,345.

As shown in the figure, the fine dust compression fixed disk 347 protrudes from the inner peripheral surface of the second dust bucket 321 toward the rotation central axis 346' of the fine dust compression rotary disk 346. The fine dust compression fixed disk 347 and the dust compression fixed disk 345 can be arranged on positions corresponding to each other.

The fine dust compression rotary disk 346 corresponds to the dust compression rotary disk 344 . The fine dust compression fixed disk 347 corresponds to the dust compression fixed disk 345 .

Since the fine dust particles are smaller than the dust particles, the fine dust pasted on the outer peripheral surface of the second dust barrel 321 may not be compressed by the fine dust compression rotating disk 346 . In order to prevent this from happening, an elastic member 348 may be incorporated at the end of the fine dust compression rotary disk 346 .

The elastic member 348 may be formed corresponding to the inner peripheral surface of the second dust bucket 321 , and is disposed between the fine dust compression rotating disk 346 and the inner peripheral surface of the second dust bucket 321 . When the fine dust compression rotary disk 346 rotates, the elastic member 348 rotates with the fine dust compression rotary disk 346 while keeping in contact with the inner peripheral surface of the second dust bucket 321 . Under the action of the elastic member 348 , the fine dust pasted on the inner peripheral surface of the second dust bucket 321 will also be compressed on the side of the fine dust compressing and fixing disk 347 .

The elastic member 348 may generate a frictional force, and the frictional force may hinder the rotation of the fine dust compression rotating disk 346 . Therefore, in order to minimize the generated frictional force, the elastic member 348 is preferably formed so as to very slightly touch the inner peripheral surface of the second dust bucket 321 .

The elastic member 348 may also be adapted to the end of the dust compression rotating disk 344 . In addition, the elastic member 348 is also applicable to the embodiments illustrated in FIGS. 3 to 8 .

The rest of the structure of the embodiment shown in FIG. 9 is similar to the embodiment illustrated in FIGS. 3 to 8 . The first cover 331 has a first sealing member 332 having a shape corresponding to the inner peripheral surface of the first dust bucket 311 to close the discharge port of the first dust storage part 310 . The second cover 333 has a second sealing member 334 having a shape corresponding to the inner peripheral surface of the second dust bucket 321 to close the discharge port of the second dust storage part 320 . The dust collecting device 400 includes a fastening portion 436 for preventing the first cover 331 from detaching from the first dust bucket 311 until the fastened state is released due to external force. The fastening part 336 combines the first dust bucket 311 and the first cover 331 at the opposite side of the hinge 335 .

Furthermore, the first rotating part 342 has a plurality of protrusions 342a radially formed from the center. In addition, the second rotating part 343 has a receiving part 343a for receiving the end part of the above-mentioned protruding part 342a on the inner peripheral surface. As the end of the protruding portion 342a is inserted into the receiving portion 343a, the first rotating portion 342 and the second rotating portion 343 are engaged with each other so as to rotate simultaneously. The protruding part 342a and the receiving part 343a may respectively have corresponding inclined surfaces 342b, 343b, so that they can slide and engage with each other by tilting at positions not fully engaged with each other.

Reference numeral 305 not explained in FIG. 9 refers to a first cyclone separator. The description of this will be replaced by the description of the first cyclone separator 205 in FIGS. 3 to 8 .

When using the dust collecting device provided by the present invention, the dust collected in the first dust storage part and the fine dust collected in the second dust storage part can be compressed, and the discharge port and the discharge port of the first dust storage part can be opened simultaneously. The outlet of the second dust storage part. The dust in the first dust storage and the fine dust in the second dust storage can be discharged at once in a compressed state. Thus, great convenience can be provided to users who need to discharge dust and fine dust.
